"I really liked Batman growing up and I came here with the intention of buying the car," Champagne, 56, told Reuters in a brief interview moments after he bought the car. "Sure enough, I was able to buy it. That was a dream come true."

Oh, he also has to pay $420,000 in premiums as well. But what's an extra $420,000 when you've already spent $4.2 million? Of course, I ask that not knowing, because, well, that's a crapload of money.

George Barris bought the car, which was based on a 1955 Lincoln Futura, for $1 in 1965 and had 15 days and $15,000 to make the Batmobile what it was currently for the show. And he's kept it ever since. That's a heck of a profit.

At the same auction, NASCAR owner Rick Hendrick picked up a couple of Corvettes for just over a cool $1 million apiece, including the first production 2014 C7 Corvette.
